Not an anarchist but no country has a good immigration policy regarding refugees. There are millions of people who are stateless or otherwise don't have a secure national environment to live in (for now largely due to first world imperialism), and no nation accepts them. Considering that this population of people needing to find new places to live is only going to increase with global warming (no matter if there is a best-case-scenario elimination of imperialism) and the most "refugee friendly" nations in the world only let in a few tens of thousands of people a year, it's fair to say that pretty much every state in the world is a total failure that must be dismantled.
